Well completion liner wiper plug

JST's ESU series stem packings, also known as u packing, are designed to be placed between the stem and bonnet of Type FC gate valves. This stem packing gives you a reliable seal for superior performance.

The FHB seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange internal face seal.

DKBI wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.

Piston seals are working to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.

A seal assembly for use in a wellbore tool, it acts as a flow restrictor protecting a lower end of the seal assembly from high pressure and/or high volume flow.

JST's Packer elements are flexible elastomeric components that are used to seal between the outside diameter of the production tubing and the casing, liner or wellbore.

This product can fully meet the pressure working conditions of current hydrogen compressor transportation equipment, ranging from 0 to 90MPa, and the sealing element will not extrude and deform, with good sealing performance.

The function of a hydraulic wear ring is to guide the piston and piston rod of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system.
